Abstract
The present application discloses a noise detecting method and apparatus, and an electronic device, the method includes: obtaining a noise of each sensing electrode of a plurality of sensing electrodes of a touch screen at a current operating frequency point during an operation of the touch screen; calculating a difference between the noise of the sensing electrode and a current noise reference of the sensing electrode to obtain a noise difference of the sensing electrode; performing differential processing on the noise differences of the sensing electrode and a noise difference of an adjacent sensing electrode of the sensing electrode, to obtain a first processing result comprising a plurality of values, and comparing a maximum value of the first processing result with a preset first threshold; if the maximum value is greater than the threshold, determining that there is noise interference at the current operating frequency point.
